FaceBook is a great tool, for keeping in contact and meeting new people with shared ideas and also people with different ideas.
I make a conscious choice about what I follow and un-follow.
Some of the “news” feeds we have little to no control over beyond simply skimming past. I know there is the option to click the “see less of”, but each time you do I notice the level increases.
To me now I use it solely to stay in touch with family and friends & follow some of the special interest groups. I don’t have the “follow” option engaged in any of them, I go to the facebook page for the groups to catch up, otherwise the timeline just gets filed with gibberish.
